In the video, the balls are scattering because the simulation makes them :-) Basically at every downward step, each ball makes a random decision about whether to go right or left. Over time, the accumulated differences in random decisions result in very different positions in space! This same effect occurs in real life in various physical devices people have created to demonstrate this mathematical truth. In those devices, the falling balls tend to impact small obstacles like pins.
IFA normal distribution in action
IFA set up (background info:This probability machine is often referred to as a Galton Board. We use it to explain the randomness of stock market returns. It produces a normal bell-shaped curve distribution from small balls dropping through strategically placed placed pins. This curve is very similar to monthly returns of the S&P 500 over 50 years. The Galton board, also known as a quincunx or bean machine, is a device for statistical experiments named after English scientist Sir Francis Galton.)
